在php中向多维数组添加数据时出错

Question

I want to read data from a data base, and put it in multi-dimensional array. I don't know number of rows that will come from data base, and when i try to add new row to the multi-dimensional array i have the following error

Warning: array_push() [function.array-push]: First argument should be an array in C:\AppServ\www\web\commands\changeservice.php on line 101

and this is the code i have

function preparenewservices()
    {

                $managername = $_SESSION['managername'];

                $sqls = "select s.*,m.* from rm_allowedmanagers m inner join rm_services s on s.srvid = m.srvid where m.managername = '$managername' ";


                $sql = mysql_query($sqls);


                 $newservices =  array();


                    while($row = mysql_fetch_array($sql))
                  {
                        $nsrvid = $row['srvid'];
                        $nsrvname = $row['srvname'];                        
                        $nunitprice = $row['unitprice'];
                        $nunitpricetax = $row['unitpricetax'];

                        $ntotal = $nunitprice + $nunitpricetax;

                        $newservice = array($nsrvid, $nsrvname , $ntotal); 

                        array_push ($newservices[count($newservices)], $newservice);

               }

    }

Answer 1

try this:

array_push ($newservices, $newservice);

instead of:

array_push ($newservices[count($newservices)], $newservice);

because now you pass to the first argument of array_push an integer value not an array
